Gypsophila plant named ‘Pearls Grandtastic’

ABSTRACT

A new Gypsophila plant particularly distinguished by very large, double flowers and an upright growth habit, is disclosed.

Genus and species: Gypsophila paniculata L.

Variety denomination: ‘Pearls Grandtastic’.

CROSS-REFERENCE TO RELATED APPLICATIONS

An application with the Community Plant Variety Rights Office was filed on Apr. 4, 2017. ‘Pearls Grandtastic’ has not been made publicly available or sold more than one year prior to the filing date of the instant application.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Gypsophila, botanically known as Gypsophila paniculata L., and hereinafter referred to by the variety name ‘Pearls Grandtastic’. ‘Pearls Grandtastic’ originated from an open-pollination conducted in Negev, Israel in April 2010 between the proprietary female Gypsophila variety ‘BL-MD-F-56’ (unpatented) and an unnamed and unpatented male Gypsophila variety.

The seeds from the cross were sown and plants were grown for evaluation, where an individual plant designated ‘Pearls Grandtastic’ was selected from the group of plants in Negev, Israel in August 2010.

In September 2010, ‘Pearls Grandtastic’ was first vegetatively propagated by side branch cuttings. ‘Pearls Grandtastic’ was found to reproduce true to type in successive generations of asexual propagation via side branch cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Negev, Israel.

-   -   1. Very large, double flowers; and     -   2. An upright growth habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Gypsophila plant is illustrated by the accompanying photograph which shows the plant's overall plant habit including form and flowers. The photograph is of a 22-week-old plant grown outdoors in Colombia in April 2016. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘Pearls Grandtastic’. The data which define these characteristics were collected from asexual reproductions carried out in Juja, Kenya. Data was collected on 20-week-old plants grown outdoors in Juja, Kenya in September 2016. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) 2007.
